Figure is. a; fulfi l 16 1" enlarged made; pnly the StiflCtHllQ pereiiientlto the co; invention Will be clescribecl.

I propose to use-are piiovideclwith two inlets, one numbered 5, fer the; 630101 and qtlien, lluIllbelQdfi; for tliea-ir curfent such in" lets may communicate ithconcentric"; duets 7 so, be employcl; and since the gun iteeli fo 'ms e pal-poi my invention and for which clafmzi is opening adjustable as to size and a plurality converging openings so designed that streams issuing therefrom will meet in the line of the central opening. The discharge of compressed air is subject to the control of a trigger 8 and when released acts to spray the color, as illustrated in Figure 1.

Detachably connected with the inlet 5, by means of a nipple and union combination 9, is a flexible hose 10 the other end of which rotatably carries a threaded collar 11 adapted to establish connection with a composite supply duct to be hereinafter described. Another hose length 12 is similarly connected with the inlet 6 and at its other end 13 with a composite air duct, description of which will follow.

A composite supportin structure or extension includes a member 14 having a bifurcated upper end to which a bellcrank lever 15 is pivoted by means of a pin 16. The lever 15 is also of forked formation and its longer arm embraces an appropriate portion of the gun 4 to which it is secured by means of bolts 17 The lower hollow end of the member 14 is.

designed for telescopic connection with another supporting section 18, (Figure 3) the upper end 19 of which is designed to enclose the lower end 01"" the member 14. The lower end20, of the section 18, is to be "similarly connected with the upper end 21 of another section .22, (Figure 4) and the lower end 23,

. ot the section 22, is in the same manner to' be I connected with the upper end 24 or another section 25, (Figure 5) The three connections just referred to as being identically eiiected are in fact, by means of the construction '11- lustrated in Figure 8, where it will be observed, for instance, that the upperend 21 carries an upwardly directed leaf spring 26 carrying a lug 27.21dapted to intersect registering holes in the ends 20 and 21 to effect an interlock thereofm 'Each of the sections 18, 22 and 25 must necessarily carry sections of correspondingly composite color and air ducts, wherefore the section 18 carries an air duct section28 and 1 a color ouct section 29, the upper ends 30 and 31 of which are threaded and adapted for detachable connection with the collars 13 and 11, respectively. The lower ends of-the ducts 28 and 29 carry collars 32 and 33 for connection with the upper ends of the two duct sections 34 and 35 which-are clamped to the section 22 and the lower ends of which are in turn to be connected with the upper ends of the ducts 36 and 3?, which in Figure 5 appear clamped to the section 25. The lower ends of the ducts 36 and 37 are detachabl connected, as shown in Figure '1, with flexible tubing 38 and 39, which are to be considered as leadingto a compressed air tank and a color containing receptacle, respectively. 7

A bracket 40 embraces the sect-ion 25 near its lower end and has pivotedon it at 41 a bellcrank lever, one arm of whichis fashioned lar 16 on the pin 16 and is attached to one end of a member 49 reciprocably connected with the arm 15 and the upper end of which is looped around-the trigger 8. The movement of the member 49 in a downward direction is against the action of a spring 50 whereand cause the spray gun to function.

Directing attention to Figure 9, it will be observed that the section 22 and duct 36 are enclosed by a Ushaped plate 51 whichis'in turn'embraced by a U shaped bracket 52 and both are secured to the section 22 by means of a pair of bolts 53:. The plate 52- carries a laterally extending bracket 54 provided with oppositely disposed slots 55. Movable, for a purpose hereinafter-explained, within the-extension 54 along the exposed side of the plate 51 is amok-56 whicha single toothed member 57 is ada-ptedto intersect. A pin 58'is passed through thetoothed plunger and through theslots whereby to prescribe the limit of its reciprocal movement. A threaded rod 59 is adjustably connected end to end with the plunger 5*? and'is surrounded by a coil spring 60-adjustably compressed by nuts 61 and normally activeto hold the tooth 011 the plunger 57 in one of the spaces of the rack.- The plunger tooth may, -however, bewithdrawn in opposition to the force ofthe spring 60, by-means'of a control lever 62, shown in'Figure 6. 'Alsoassociated with the bracket 52, in the manner disclosed in Figure 10, is a squared shaft 63 on which is carried apinion-64 so as't'o be in'mesh with the rack 56. A. projecting end of the shaft 63 carries a handled crank 65, whereby the pinion may be turned to reciprocate the rack whenever the lever 62' has withdrawn the locktooth of the plunger 57 from its functioning position. One end of the rack 56 is connected with a series of detachably articulated rods 66, each of whichis guided by passing'through ears 67,- 68' EL11d 69, which project fromthe sections 25, 22 and 18, respectively. The rods 66 are linked together through the agency of pins 70, as shown in Figurel. The uppermost rod 71 is very. short and is pivotally connected at 72-with the other arm'of the bellc'rank lever'15.
